I didn’t try it myself, but according to the documentation both forms that you used are not allowed (upper case, uncompressed ‘::’): 2001:0DB8::/32 2001:0db8:0000:0000:0000:0000:0000:0000/32 Can you try one of the following instead, and see if it works? In any case IPv6 CIDR notation should be supported in OpenDKIM. 2001:0db8::/32 2001:db8::/32 [2001:0db8::]/32 [2001:db8::]/32
